In selection and design of materials for tribological applications, high resistance to material damage or least surface deterioration of the contacting surfaces is of considerable interest. The present work deals with the study of the wear properties investigated under fretting condition of Al65Cu20Ti15 composite containing finely distributed intermetallic compounds, fabricated by mechanical alloying followed by pulse plasma sintering (PPS) process. The wear experiments were carried out in gross slip fretting conditions to investigate the wear performance of the composite against the Al2O3 balls with ambient conditions of temperature (24 ± 2°C) and humidity (50 ± 5%).
